I was following this and racking my brain. Thanks for the update and I'm glad you got it sorted.

Re: Check Engine Light, goes off @ 4000 ish rpms

Ok I'm going to throw this out there and it is what I'm thinking, not what I know for certain but it may be worth discussing... Could an O2 sensor be at fault, one that is configured in the ECU to go open loop at above 4200rpm so it would stop reporting a fault over this rpm? Is there another sensor...

Re: Syncing throttle bodies question

You definitely need a tool to measure the air flow as shown by OST The important thing is to adjust the linkage off of idle. A way to do this is to open the throttle a small set amount, this can be done by wedging the cable open. Then you need to adjust the linkages so that each itb reads the same. ...

No assumption required, anyone who builds an engine and is then surprised by the compression ratio...

"I ran a compression test on the cylinders and they all read high, really high, like 15 bar high"

Re: HIGH comp Big port carby build with MANY questions

I guess you built this engine to give more power than standard... otherwise why bother? At least two of your questions would be answered by taking the engined to a dyno / rolling road, 98 octane fuel and a good AFR. The weak point of the 4age? The person who tunes it.

Re: 20V silvertop potential.

What you gain in revs you lose in low down torque compared to your 2.0
The cams you are considering are only marginally more aggressive than standard. Expect to see similar WHP figures to what you already have unless you go for a fully prepared competition engine where over 200hp is possible.

Re: Surging idle

It could be that the TPS needs setting again. There is an idle switch in the TPS that must be engaged when idling if the switch is not engaged the fuel calibration from the ecu is wrong. This is relatively easy to check for free and the best way I have found is first to accurately scribe the current...

Re: Surging idle

Is this an engine conversion or did the car come with installed engine from the factory? If it is factory then it could be the TPS. Try doing a diagnostic test and report results.

With the diagnostic port shorted you should get a steady flashing of the engine management light (EML) on the dashboard, it should not be on solid.

Re: AE86 Rough Start up

It sounds like it is over fuelling but I'm not sure that there is an error code for that when the engine is first started as the O2 sensor is not reporting. Have you checked for stored error codes? Maybe try disconnecting the cold start injector to see if there is a difference?

Be careful with the universal AEM - 4 ecu if you want to run it with the original distributor sensors, the VR signals need reversing and the universal AEM cannot do this.
